If you'll notice though, on that site, everyone pictured is white and most have straight, unkinky hair. If you're already blessed with an afro, you should just let it go. No more picking, no more combing. I've got really dry curly hair which began to lock up on its own once it got pretty long. My queen's hair, too, locked up naturally. She too is white and has "white" hair. Break the comb, and you'll be fine.
